Other Notes ΔUA = 4-deoxy-L-threo-hex-4-enopyranosyluronic acid; GlcNAc = N-acetyl-D-glucosamine Preparation Note Product of digestion of hyaluronic acid by chondroitinase.
Other Notes ΔUA = 4-deoxy-L-threo-hex-4-enopyranosyluronic acid; GalNAc = N-acetyl-D-galactosamine Application Chondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans.
